After planting in spring, dry in the air for 60 ~ 70 cm. Weak seedlings can appropriately reduce the fixed stem height. When planting in spring and pruning in winter, the extension branches of the central trunk can be cut off by 30 ~ 40 cm, and then cut off by 40 ~ 50 cm every year, which will hurt the third and fourth buds under the cut when sprouting. At the same time, 2 ~ 3 strong long branches are selected as small main branches, and 1 ~ 2 small main branches can be left in the second winter cutting, and 1 small main branches can be left every year thereafter. The selected small main branches can be moderately shortened when the buds are full in the first year of winter, and then slowly released every year. In order to promote them to send out lateral medium-long branches and cultivate them into medium-sized branches, eye injuries can be carried out at a bud spacing of about 30 cm every year; The opening angle is 60 in the second year after being elected as a small master.

For long branches (auxiliary branches) without small main branches on the central trunk, they should generally be laid flat and long, and the angle of the second bud branches is small, which can be pulled into a "reverse bow", and then recovered and cultivated into medium-sized branches. If there are many short branches on the central trunk, and the medium-sized branches are short of long branches, you can hurt your eyes above the short branches and make them grow medium-long branches. Try not to thin branches or few branches during plastic surgery, so as to increase the number of branches as soon as possible and achieve early and high yield.

By the age of 4 ~ 5, 6 ~ 7 small branches can be formed on the central trunk, and plastic surgery is basically completed. After that, it is mainly to deal with the long branches standing upright in the crown and retract the long branches to prevent the crown from closing. When it is 6 ~ 8 years old, it enters a large number of fruiting periods, and when the yield of small branches in the upper layer is high, it can happily hang its head above the last main branch. After that, in addition to preventing the crown from closing, we should also pay attention to adjusting the balance between small main branches to control the crown from expanding too much.
